In my printer, I have an incorrect distance between the two Z axis extrusions, so the x gantry was stuck at the bottom and very loose at top of Z height causing level problems and bindings. I don´t know if this is machining problem only in my printer but maybe this can help to someone else.
I put this spacer in the left side of the printer (in my case 1.2mm thick, you can modify to your needs) so now the x gantry can run smootly along the z axis.
The file has 0.8mm thick, but you can scale it (only height) to your needs).
